215534-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215534-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,5,3 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 215534-68:
(8*2)+(7*1)+(6*5)+(5*5)+(4*3)+(3*4)+(2*6)+(1*8)=122
122 % 10 = 2
So 215534-68-2 is a valid CAS Registry Number.

Design and synthesis of novel conformationally restricted peptide secondary structure mimetics
Kim, Hwa-Ok,Nakanishi, Hiroshi,Lee, Min S.,Kahn, Michael
, p. 301 - 302 (2007/10/03)
(matrix presented) A facile synthesis of the novel conformationally restricted reverse turn mimetic is described. The key features are the preparation of the α-keto amide and tandem bicyclic ring formation.
